Specification ofrLetters Patent. Patented. Apr. 16,

Application led February 23, 1917. Serial o. 150,369.

To all whom it may conce/m:

Be it known that I, HARRY C. Srnnnrnn a citizen of the United States, residing at Bristol, in the county of Bucks and State of Pennsylvania, have invented certain new and useful improvements in inclosures for Boilers and Heaters, ci which the following is a specification.

Myinvention consists of an improved in closure for boilers and heaters. One object of my invention is to prevent the hot gases of combustion from passing directly fromtheboiler or heater up the chimney.

Another object of my invention is to so construct my improved inclosure that said h'ot gases will be compelled to pass entirely around and in contact with the outer' surface 0f theboiler or heater prior to passing up the chimney/,and thus retain the heat within the boiler or heater at a high temperature. I' Another object is to so construct my in vention that it'can be readily adapted to t various vtypes of boilers and heaters now on the market and in common use.' j

' Adm-ther object is to make my invention osimple construction and so that the parts thereof can be easily removed for repair or cleaning purposes.

These objects7 and other" advantageous ends which Will be' described hereinafter, I attain in the following manner, reference bein0'had to the accompanying /drawings in which 'Figure 1 is a front elevation of my invention attached to a heaterv such for example as ahot water heater ofv a type now y in common use for heating buildings.

Fig. 2 is a section on the line 2 2 of lstig. 3 is a section on the line 3-3 of Fig. 2 showing the heater in outside elevation.

Fig. i is a transversesection on the line Mott Fig. 1.

Fig. 5 is atransverse section on the line 5 5 (if-Big. 1.

' Fi 6 is a perspective/view of one of the' side ao invention. Fig. 'I is a fragmentary sectional elevation showing a modification of my invention2 and i l Fig. 8 is a transverse section on the line 8-8 of Fig. T.

Re'aerrin to the drawings, the body portion "l of t e heater is supported on a base 2 which is preferably made hollow to replates which forms a part of my ceive the ashes and is provided with a door 3 which covers an opening l through which the ashes may be removed from time to time..

The usual fuel supply opening 5 is provided, as well as the opening l6, through which clinkers may be removed from Vthe 'A grate level of the heater.v The upper porp tion of the heater in the present instance is provided with an opening Z which forms an hutlet for the hot gases and other products of combustion, this being the opening which f` l is ordinarily attached to the chimney by a 'f pipe including `a damper to regulate the draft. However, in my present invention l eliminate this direct connection between the opening 7 and the chimneyv as will be more clearly understood from the following description. Y

The base 2 forms a support for a jacket 8 which is substantially cylindrical and includes a liront section 9 anda rear motion 10. This jacket is of substantiallygreater .internal diameter than the external diameter of the body portion 1 of the .heater and rated at 13 tol permit the water circulating,

pipes. 14 of the heater to through.

The sections extend therea 9 and 10 have outwardly `is also of greater height, thus providing a v Y es' j projecting flanges 15 and 16 respectively between which are secured two longitudi- 1 nally extending bail'le plates 17. These baiiie plates are arranged diametrically op'- posite in the present instance andv have their outer edge portions 18 extending the full length of the anges'i and 16.

Bolts 19 pass through the anges 15 and of the baile plates 175 thereby securing the latter and also joining the front and rear sections.

' Each of the baile plates i7 has a wing 2O which'extends inwardly and into direct contact with the outer surface of the body portion l of the heater (see Figs. l, 3, and 5). The wings 20 are of shorterlength than the portions 18 and form passa eways 21 between the compartment 22 of t e section 9 and the compartment of the lsection 10, it being noted that the provision of said baille plates 17 divides the chamber 8 into 16 and also through the edge portions 18 the said compartments 22 and 23 and the passages 21 form communication between the compartments 22 and 23 adjacent the H38. In a similar manner, jt 55."

lowermost portion or' heater'. l

A segmental baille 24 covers and forms a top for the upper portion olf' the compartment 23, and this baille is in the form of a half ring, the yends 25 of which extend over the vupper edges 26 of the.bailie wings 20 (see Figs. 1, 2, 3, and 4). The edges 26 of saidbaiilewings 20 are substantially on a level with the top surface 27 of the heater body 1, so that an upper compartment 28 is provided between the cover 12 andthe upper surface 27 of the heater body 1. The segmental baffle 24 has an opening 29 which isy normally lclosed by a damper 30, the latter being pivotally supported on the baiiie 24 and has a rod 31 which extends through the rear section 10 to the outside `of said jacket and is provided with a handle 32, whereby the damper lmay be opened if desired. v

The rear section y10 has an openin` 33 which comn'iunicates with a pipe 34 'W ich leads to the chimney, said pipe having a regulating damper 35. Another damper 86 is formed within the pipe 34 and when open, the pipe 34 will communicate with the atmosphere immediately surrounding the jacket 8, so that the intensity of the draft may also be regulated by the damper 36.

The front section 9 ias an opening 37 for the reception of a sleeve 38, the latter having outer flanges 39 which abut the outer surface of the front section. 9, said sleeve fitting Within the fire door opening the body 1 of the within the body 1 of the heater, thus permitting fuel to be suppliedto the heater and providing a seal to prevent the heated gases from escaping lthrough the opening 37. In like manner, a sleeve 40 is inserted through an opening 41 adjacent the bottom of the front section 9, said sleeve entering the clinker opening 6. This sleeve 40 is also provided with an outer flange 42 which limits the inward movement of the sleeve and also forms a seal to prevent the escape of gases. j

A fire door 43 is hinged to the front section 9 and acts as a closure for the sleeve a door 44 forms closure for the sleeve 40. l Nfl," le operation of my invention is as folgases from passing into the compartment 23 until they have completely passed down the front half of the body 1 of the heater.

Afterpassing to the bottom of said body portion 1 of the heater, they pass 'throu hthe passages 21 and upwardly through t e compartment 23, thence outwardly through `the pipe 34. It will thus be noted that I secure a circulation of the heated gases entirely varound and incontact with the outer surface of the body portion 1 of the heater prior to their passin to the chimney, thus the outer surface of t e body portion l of the heater is kept extremely hot and adds' to .the efficiency of said heater in performing its 'function of circulating, in the present instance, the water. through the pipes 14 and the water is kept at a higher temperature than if the heated gas 'was allowed to directly ass from the opening 7 to the chimney without first performing the function of providing a heating medium between the jacket and the'outer surface .of said body portion 1 of the heater.

If, for any purpose/it is desired to have a direct draft between the opening 7 and the chimney, the `damper 30 may be opened and the movementl of the gases `will then be directly through the opening -29 and pipe34 to the chimney.

In the modification shown in Figs. 7 and 8,

I have shown a bottom 45 for the jacket. l

This bottom is designed to rest upon the lbase 2 of the heater and has an upwardly pro l jecting iange 46 which is bolted to the lower edge portions of the jacket 8. The bottom 45 is preferably made in two sections to permit'the edge portionsv 18 of the side baille plates 17 to project therebetween as well as the flanges 15 andl of the jacket sections 9 and 10. This-bottom 45 is of value when the bas'e`2l of the heater is comparatively nar-v row as illustrated in Fig. 7, so that said bottom forms a projection or extension to provide the support for said jacket which mustv necessarily be of larger diameter than the body portion 1 of the heater.

The advantage or' my invention is two/ fold. It keeps the heater proper'at a higher temperature, and it also heats the surrounding atmosphere, and is therefore of exceptional value when attached to heaters 1n dwelling houses or other buildingswhicly re located in the cellar, since it keeps the warm and dry. While'I have described my invention as taking a particular form, it will be understoodv that the various parts of my invention may be chan ed without departing from vthe spirit thereo and hence I do not limit my` self to the'precise construction setforth,but consider that I am at liberty to make such changes and/alterations,aslfairly come within the scope of the ap circled claims. i

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combinationof a heater havin an outlet opening for the products Ofcom ustion, a jacket surrounding said heater and spaced therefrom to provide a chamber, said jacket being made in a plurality ol sections and having outwardly projecting flanges, baille plates having outer edge portionsl secured between said flanges and having their inner portions extending across said chanr ber and into engagement with said heater, said latter portions ofthe baille plates being interrupted in their length at opposite ends t0 divide the chamber into a number ofi compertinents and to provide Va passageway forming communication between the compartments at a position remote from said outlet openin ,of the heater, another baille connecting said baille plates and forming a closure for certain of said compartments be tween said outlet opening of the heater and s'aid remote passageway, said jacket having an outlet opening adjacent said second baille, substantially as described.

2. The combination'of a heater having an outlet opening for the products oi combus tion, a jacket surrounding said heater and spaced therefrom to provide a chamber, said jacket being made in a plurality of sections, said sections being detacliably secured together, baille plates having outcredge por- I tions secured between said sections. and having wing portions extending into engagement with said heater, a segmental baille spaced below the top of the jacket extending from said wings and separating saidoutlet opening of the heater from one of said com i partments, said jacket having an opening be low vthe segmental baille leading from said latter compartment, said bame plates providing a passage between said compartments whereby the products of combustion are compelled to pass around and in contact with the outer surface of said heater prior to passing out of the opening in the jacket, substantially as described.

3. Thecombination of aheater having an outlet opening-for the roducts of combustion, a jacket surrounding said heater and spaced therefrom to provide a chamber, said jacket being made in a plurality of sections,
